Plugin does not return Original Transaction Identifier when restoring purchases (at least on iOS).

[haninaguib]

I think this information should be returned. I would want to use it as part of a key used to generate request tokens to my server.

Original transaction id is most important detail of Subscription. restorePurchases should return original_transaction_id in IOS. I agree that.

I'm testing on Android, returned transactionId is empty!

Hi, I was stuck with this too. My solution is:

• purchase time: store the product info when buying in my server's database, which has the transactionId
• restore time:
  • call the getReceipt() in client
  • send the receipt to my server API
  • verify the receipt server side, as explained here https://developer.apple.com/library/archive/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html#//apple_ref/doc/uid/TP40010573-CH104-SW1
  • call the store using https://github.com/awa/go-iap/blob/master/appstore/validator.go#L99
  • check the subscription is not expired
  • parse the original transaction ID from the response (see returned fields at https://developer.apple.com/library/archive/releasenotes/General/ValidateAppStoreReceipt/Chapters/ReceiptFields.html)
  • check that the original transaction ID is in the database (should match the one store in the first bullet point - at purchase time)

How can I do that with a non consumable product? There is no entry in the "in_app" array in the response of getReceipt(). Thanks.

@haninaguib getting the same behavior apparently this is expected.. see SO answer Question is - is there a way to by pass it with this library as explained natively in the above SO answer
